DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

In the formula (I) and all the formulae which follow, alkyl radicals having more than two carbon atoms may be straight-chain or branched. Alkyl radicals are, for example, methyl, ethyl, n- or isopropyl, n-, iso-, tert- or 2-butyl, pentyls, hexyls such as n-hexyl, isohexyl and 1,3-dimethylbutyl. Halogen is fluorine, chlorine, bromine or iodine.

Heterocyclyl is a saturated, semisaturated or fully unsaturated cyclic radical containing 3 to 6 ring atoms, of which 1 to 4 are from the group of oxygen, nitrogen and sulfur, and which may additionally be fused by a benzo ring. For example, heterocyclyl is piperidinyl, pyrrolidinyl, tetrahydrofuranyl, dihydrofuranyl and oxetanyl.

Heteroaryl is an aromatic cyclic radical containing 3 to 6 ring atoms, of which 1 to 4 are from the group of oxygen, nitrogen and sulfur, and which may additionally be fused by a benzo ring. For example, heteroaryl is benzimidazol-2-yl, furanyl, imidazolyl, isoxazolyl, isothiazolyl, oxazolyl, pyrazinyl, pyrimidinyl, pyridazinyl, pyridinyl, benzisoxazolyl, thiazolyl, pyrrolyl, pyrazolyl, thiophenyl, 1,2,3-oxadiazolyl, 1,2,4-oxadiazolyl, 1,2,5-oxadiazolyl, 1,3,4-oxadiazolyl, 1,2,4-triazolyl, 1,2,3-triazolyl, 1,2,5-triazolyl, 1,3,4-triazolyl, 1,2,4-triazolyl, 1,2,4-thiadiazolyl, 1,3,4-thiadiazolyl, 1,2,3-thiadiazolyl, 1,2,5-thiadiazolyl, 2H-1,2,3,4-tetrazolyl, 1H-1,2,3,4-tetrazolyl, 1,2,3,4-oxatriazolyl, 1,2,3,5-oxatriazolyl, 1,2,3,4-thiatriazolyl and 1,2,3,5-thiatriazolyl.

When a group is polysubstituted by radicals, this means that this group is substituted by one or more identical or different radicals from those mentioned.

According to the nature and the bonding of the substituents, the compounds of the general formula (I) may be present as stereoisomers. When, for example, one or more asymmetric carbon atoms are present, enantiomers and diastereomers may occur. Stereoisomers likewise occur when n is 1 (sulfoxides). Stereoisomers can be obtained from the mixtures obtained in the preparation by customary separation methods, for example by chromatographic separation processes. It is equally possible to selectively prepare stereoisomers by using stereoselective reactions using optically active starting materials and/or auxiliaries. The invention also relates to all stereoisomers and mixtures thereof which are encompassed by the general formula (I) but not defined specifically.

Inventive compounds can be prepared, for example, by the method shown in scheme 1, by base-catalyzed reaction of a pyridinecarbonyl chloride (II) with a 4-amino-1,2,5-oxadiazole (III):

The pyridinecarbonyl chlorides of the formula (II) or their parent pyridinecarboxylic acids are known in principle and can be prepared, for example, by the methods described in WO 03/106448 A2, WO 01/94339 A1 and WO 01/54501 A2.

Inventive compounds can also be prepared by the method described in scheme 2, by reacting a pyridinecarboxylic acid of the formula (IV) with a 4-amino-1,2,5-oxadiazole (III):

For the activation, it is possible to use dehydrating reagents which are typically used for amidation reactions, for example 1,1′-carbonyldiimidazole (CDI), dicyclohexylcarbodiimide (DCC), Mukaiyama reagent on polymer support according to M. Wittaker et al; Tet. Lett. 45(17), 3401-3404 (2004), 2,4,6-tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide (T3P) etc.

The 4-amino-1,2,5-oxadiazoles of the formula (III) are either commercially available or known, or can be prepared analogously to methods known from the literature. For example, 3-alkyl-4-amino-1,2,5-oxadiazoles can be prepared from β-keto esters by the method described in Russian Chemical Bulletin, Int. Ed., vol. 54, 4, p. 1032-1037 (2005):

In the abovementioned formula, R is, for example, an alkyl or phenyl radical. 3-Aryl-4-amino-1,2,5-oxadiazoles can be synthesized, for example, as described in Russian Chemical Bulletin, 54(4), 1057-1059, (2005) or Indian Journal of Chemistry, Section B: Organic Chemistry Including Medicinal Chemistry, 26B(7), 690-2, (1987):

3-Amino-4-halo-1,2,5-oxadiazoles can be prepared, for example, from the commercially available 3,4-diamino-1,2,5-oxadiazole by the method described in Heteroatom Chemistry 15(3), 199-207 (2004):

Nucleophilic R radicals can be introduced into 3-amino-1,2,5-oxadiazoles of the general formula V by substitution of the leaving group L (L is, for example, halogen, triflate, nitro) as described in Journal of Chemical Research, Synopses, (6), 190, 1985 or in or Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, (9), 2086-8, 1986 or in Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya), 53(3), 596-614, 2004:

Collections of compounds of the formula (I) and/or salts thereof which can be synthesized by the abovementioned reactions can also be prepared in a parallelized manner, in which case this may be accomplished in a manual, partly automated or fully automated manner. It is possible, for example, to automate the conduct of the reaction, the workup or the purification of the products and/or intermediates. Overall, this is understood to mean a procedure as described, for example, by D. Tiebes in Combinatorial Chemistry—Synthesis, Analysis, Screening (editor: Günther Jung), Wiley, 1999, on pages 1 to 34.

For the parallelized conduct of the reaction and workup, it is possible to use a number of commercially available instruments, for example Calypso reaction blocks from Barnstead International, Dubuque, Iowa 52004-0797, USA or reaction stations from Radleys, Shirehill, Saffron Walden, Essex, CB11 3AZ, England, or MultiPROBE Automated Workstations from Perkin Elmer, Waltham, Mass. 02451, USA.

For the parallelized purification of compounds of the general formula (I) and salts thereof or of intermediates which occur in the course of preparation, available apparatuses include chromatography apparatuses, for example from ISCO, Inc., 4700 Superior Street, Lincoln, Nebr. 68504, USA.

The apparatuses detailed lead to a modular procedure in which the individual working steps are automated, but manual operations have to be carried out between the working steps. This can be circumvented by using partly or fully integrated automation systems in which the respective automation modules are operated, for example, by robots. Automation systems of this type can be purchased, for example, from Caliper, Hopkinton, Mass. 01748, USA.

The implementation of single or multiple synthesis steps can be supported by the use of polymer-supported reagents/scavenger resins. The specialist literature describes a series of experimental protocols, for example in ChemFiles, Vol. 4, No. 1, Polymer-Supported Scavengers and Reagents for Solution-Phase Synthesis (Sigma-Aldrich).

Aside from the methods described here, the compounds of the general formula (I) and salts thereof can be prepared completely or partially by solid-phase supported methods. For this purpose, individual intermediates or all intermediates in the synthesis or a synthesis adapted for the corresponding procedure are bound to a synthesis resin. Solid-phase supported synthesis methods are described adequately in the technical literature, for example Barry A. Bunin in “The Combinatorial Index”, Academic Press, 1998 and Combinatorial Chemistry—Synthesis, Analysis, Screening (editor: Günther Jung), Wiley, 1999. The use of solid-phase-supported synthesis methods permits a number of protocols known from the literature, and these may again be executed manually or in an automated manner. The reactions can be performed, for example, by means of IRORI technology in microreactors from Nexus Biosystems, 12140 Community Road, Poway, Calif. 92064, USA.

Either on a solid phase or in the liquid phase, the performance of single or multiple synthesis steps can be supported by the use of microwave technology. The technical literature describes a number of experimental protocols, for example Microwaves in Organic and Medicinal Chemistry (editors: C. O. Kappe and A. Stadler), Wiley, 2005.

The preparation by the processes described here gives compounds of the formula (I) and salts thereof in the form of substance collections, which are called libraries. The present invention also provides libraries comprising at least two compounds of the formula (I) and salts thereof.

The inventive compounds of the formula (I) (and/or salts thereof), collectively referred to hereinafter as “inventive compounds”, have excellent herbicidal efficacy against a broad spectrum of economically important monocotyledonous and dicotyledonous annual harmful plants. The active ingredients also have good control over perennial harmful plants which are difficult to control and produce shoots from rhizomes, root stocks or other perennial organs.

The present invention therefore also provides a method for controlling unwanted plants or for regulating the growth of plants, preferably in plant crops, in which one or more inventive compound(s) is/are applied to the plants (for example harmful plants such as monocotyledonous or dicotyledonous weeds or unwanted crop plants), to the seeds (for example grains, seeds or vegetative propagules such as tubers or shoot parts with buds) or to the area on which the plants grow (for example the area under cultivation). The inventive compounds can be deployed, for example, prior to sowing (if appropriate also by incorporation into the soil), prior to emergence or after emergence. Specific examples of some representatives of the monocotyledonous and dicotyledonous weed flora which can be controlled by the inventive compounds are as follows, though the enumeration is not intended to impose a restriction to particular species:

Monocotyledonous harmful plants of the genera: Aegilops, Agropyron, Agrostis, Alopecurus, Apera, Avena, Brachiaria, Bromus, Cenchrus, Commelina, Cynodon, Cyperus, Dactyloctenium, Digitaria, Echinochloa, Eleocharis, Eleusine, Eragrostis, Eriochloa, Festuca, Fimbristylis, Heteranthera, Imperata, Ischaemum, Leptochloa, Lolium, Monochoria, Panicum, Paspalum, Phalaris, Phleum, Poa, Rottboellia, Sagittaria, Scirpus, Setaria, Sorghum.

Dicotyledonous weeds of the genera: Abutilon, Amaranthus, Ambrosia, Anoda, Anthemis, Aphanes, Artemisia, Atriplex, Bellis, Bidens, Capsella, Carduus, Cassia, Centaurea, Chenopodium, Cirsium, Convolvulus, Datura, Desmodium, Emex, Erysimum, Euphorbia, Galeopsis, Galinsoga, Galium, Hibiscus, Ipomoea, Kochia, Lamium, Lepidium, Lindernia, Matricaria, Mentha, Mercurialis, Mullugo, Myosotis, Papaver, Pharbitis, Plantago, Polygonum, Portulaca, Ranunculus, Raphanus, Rorippa, Rotala, Rumex, Salsola, Senecio, Sesbania, Sida, Sinapis, Solanum, Sonchus, Sphenoclea, Stellaria, Taraxacum, Thlaspi, Trifolium, Urtica, Veronica, Viola, Xanthium.

If the inventive compounds are applied to the soil surface before germination, either the weed seedlings are prevented completely from emerging or the weeds grow until they have reached the cotyledon stage, but then stop growing and, eventually, after three to four weeks have passed, die completely.

If the active ingredients are applied post-emergence to the green parts of the plants, there is likewise stoppage of growth after the treatment, and the harmful plants remain at the growth stage of the time of application, or they die completely after a certain time, such that competition by the weeds, which is harmful to the crop plants, is thus eliminated very early and in a lasting manner.

Although the inventive compounds have excellent herbicidal activity against monocotyledonous and dicotyledonous weeds, crop plants of economically important crops, for example dicotyledonous crops of the genera Arachis, Beta, Brassica, Cucumis, Cucurbita, Helianthus, Daucus, Glycine, Gossypium, Ipomoea, Lactuca, Linum, Lycopersicon, Nicotiana, Phaseolus, Pisum, Solanum, Vicia, or monocotyledonous crops of the genera Allium, Ananas, Asparagus, Avena, Hordeum, Oryza, Panicum, Saccharum, Secale, Sorghum, Triticale, Triticum, Zea, especially Zea and Triticum, are damaged only to an insignificant extent, if at all, depending on the structure of the respective inventive compound and the application rate thereof. For these reasons, the present compounds are very suitable for selective control of unwanted plant growth in plant crops such as agriculturally useful plants or ornamentals.

In addition, the inventive compounds (depending on their particular structure and the application rate deployed) have outstanding growth-regulating properties in crop plants. They intervene in the plant's own metabolism with a regulatory effect, and can thus be used to control plant constituents and to facilitate harvesting, for example by triggering desiccation and stunted growth. In addition, they are also suitable for general control and inhibition of unwanted vegetative growth without killing the plants. Inhibiting vegetative growth plays a major role for many monocotyledonous and dicotyledonous crops, since, for example, this can reduce or completely prevent lodging.

By virtue of their herbicidal and plant growth-regulating properties, the active ingredients can also be used for control of harmful plants in crops of genetically modified plants or plants modified by conventional mutagenesis. In general, the transgenic plants are notable for special advantageous properties, for example for resistances to certain pesticides, in particular certain herbicides, resistances to plant diseases or organisms that cause plant diseases, such as certain insects or microorganisms such as fungi, bacteria or viruses. Other particular properties relate, for example, to the harvested material with regard to quantity, quality, storability, composition and specific constituents. For instance, there are known transgenic plants with an elevated starch content or altered starch quality, or with a different fatty acid composition in the harvested material.

With regard to transgenic crops, preference is given to the use of the inventive compounds in economically important transgenic crops of useful plants and ornamentals, for example of cereals such as wheat, barley, rye, oats, millet/sorghum, rice and corn, or else crops of sugar beet, cotton, soybean, oilseed rape, potato, tomato, peas and other vegetables. Preferably, the inventive compounds can be used as herbicides in crops of useful plants which are resistant, or have been made resistant by recombinant means, to the phytotoxic effects of the herbicides.

Preference is given to the use of the inventive compounds or salts thereof in economically important transgenic crops of useful plants and ornamentals, for example of cereals such as wheat, barley, rye, oats, millet/sorghum, rice, cassava and corn, or else crops of sugar beet, cotton, soybean, oilseed rape, potato, tomato, peas and other vegetables. Preferably, the inventive compounds can be used as herbicides in crops of useful plants which are resistant, or have been made resistant by recombinant means, to the phytotoxic effects of the herbicides.

Conventional ways of producing novel plants which have modified properties in comparison to existing plants consist, for example, in traditional breeding methods and the generation of mutants. Alternatively, novel plants with modified properties can be generated with the aid of recombinant methods (see, for example, EP-A-0221044, EP-A-0131624). For example, there have been many descriptions of:

-   -   recombinant modifications of crop plants for the purpose of         modifying the starch synthesized in the plants (e.g. WO         92/11376, WO 92/14827, WO 91/19806),     -   transgenic crop plants which are resistant to particular         herbicides of the glufosinate type (cf., for example,         EP-A-0242236, EP-A-242246) or glyphosate type     -   (WO 92/00377) or the sulfonylureas (EP-A-0257993, U.S. Pat. No.         5,013,659), transgenic crop plants, for example cotton, with the         ability to produce Bacillus thuringiensis toxins (Bt toxins)         which make the plants resistant to particular pests         (EP-A-0142924, EP-A-0193259),     -   transgenic crop plants with a modified fatty acid composition         (WO 91/13972),     -   genetically modified crop plants with novel constituents or         secondary metabolites, for example novel phytoalexins, which         cause an increased disease resistance (EPA 309862, EPA0464461),     -   genetically modified plants with reduced photorespiration, which         have higher yields and higher stress tolerance (EPA 0305398),     -   transgenic crop plants which produce pharmaceutically or         diagnostically important proteins (“molecular pharming”),     -   transgenic crop plants which are notable for higher yields or         better quality,     -   transgenic crop plants which are notable for a combination, for         example, of the abovementioned novel properties (“gene         stacking”).

Numerous molecular biology techniques which can be used to produce novel transgenic plants with modified properties are known in principle; see, for example, I. Potrykus and G. Spangenberg (eds.), Gene Transfer to Plants, Springer Lab Manual (1995), Springer Verlag Berlin, Heidelberg or Christou, “Trends in Plant Science” 1 (1996) 423-431).

For such recombinant manipulations, nucleic acid molecules which allow mutagenesis or a sequence change by recombination of DNA sequences can be introduced into plasmids. With the aid of standard methods, it it possible, for example, to undertake base exchanges, remove parts of sequences or add natural or synthetic sequences. For the connection of the DNA fragments to one another, it is possible to add adapters or linkers to the fragments; see, for example, Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, 2nd ed., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y.; or Winnacker “Gene and Klone”, VCH Weinheim, 2nd edition, 1996.

The production of plant cells with a reduced activity of a gene product can be achieved, for example, by the expression of at least one appropriate antisense RNA, or of a sense RNA for achievement of a cosuppression effect, or the expression of at least one appropriately constructed ribozyme which specifically cleaves transcripts of the abovementioned gene product. To this end, it is possible to use DNA molecules which encompass the entire coding sequence of a gene product inclusive of any flanking sequences which may be present, and also DNA molecules which only encompass portions of the coding sequence, it being necessary for these portions to be long enough to have an antisense effect in the cells. The use of DNA sequences which have a high degree of homology to the coding sequences of a gene product, but are not completely identical to them, is also possible.

When expressing nucleic acid molecules in plants, the protein synthesized can be localized in any desired compartment of the plant cell. However, in order to achieve localization in a particular compartment, it is possible, for example, to join the coding region to DNA sequences which ensure localization in a particular compartment. Such sequences are known to those skilled in the art (see, for example, Braun et al., EMBO J. 11 (1992), 3219-3227; Wolter et al., Proc. Natl. Acad. Sci. USA 85 (1988), 846-850; Sonnewald et al., Plant J. 1 (1991), 95-106). The nucleic acid molecules can also be expressed in the organelles of the plant cells.

The transgenic plant cells can be regenerated by known techniques to give whole plants. In principle, the transgenic plants may be plants of any desired plant species, i.e. both monocotyledonous and dicotyledonous plants.

Thus, it is possible to obtain transgenic plants whose properties are altered by overexpression, suppression or inhibition of homologous (=natural) genes or gene sequences, or expression of heterologous (=foreign) genes or gene sequences.

Preferably, the inventive compounds can be used in transgenic crops which are resistant to growth regulators, for example dicamba, or to herbicides which inhibit essential plant enzymes, for example acetolactate synthases (ALS), EPSP synthases, glutamine synthases (GS) or hydroxyphenylpyruvate dioxygenases (HPPD), or to herbicides from the group of the sulfonylureas, the glyphosates, glufosinates or benzoylisoxazoles and analogous active ingredients.

On employment of the inventive active ingredients in transgenic crops, not only do the effects toward harmful plants observed in other crops occur, but often also effects which are specific to application in the particular transgenic crop, for example an altered or specifically widened spectrum of weeds which can be controlled, altered application rates which can be used for the application, preferably good combinability with the herbicides to which the transgenic crop is resistant, and influencing of growth and yield of the transgenic crop plants.

The invention therefore also provides for the use of the inventive compounds as herbicides for control of harmful plants in transgenic crop plants.

The inventive compounds can be applied in the form of wettable powders, emulsifiable concentrates, sprayable solutions, dusting products or granules in the customary formulations. The invention therefore also provides herbicidal and plant growth-regulating compositions which comprise the inventive compounds.

The inventive compounds can be formulated in various ways, according to the biological and/or physicochemical parameters required. Examples of possible formulations include: wettable powders (WP), water-soluble powders (SP), water-soluble concentrates, emulsifiable concentrates (EC), emulsions (EW), such as oil-in-water and water-in-oil emulsions, sprayable solutions, suspension concentrates (SC), oil- or water-based dispersions, oil-miscible solutions, capsule suspensions (CS), dusting products (DP), seed-dressing products, granules for broadcasting and soil application, granules (GR) in the form of microgranules, sprayable granules, coated granules and adsorption granules, water-dispersible granules (WG), water-soluble granules (SG), ULV formulations, microcapsules and waxes.

These individual types of formulation are known in principle and are described, for example, in: Winnacker-Küchler, “Chemische Technologie” [Chemical Technology], volume 7, C. Hanser Verlag Munich, 4th edition 1986, Wade van Valkenburg, “Pesticide Formulations”, Marcel Dekker, N.Y., 1973; K. Martens, “Spray Drying” Handbook, 3rd ed. 1979, G. Goodwin Ltd. London.

The necessary formulation auxiliaries, such as inert materials, surfactants, solvents and further additives are likewise known and are described, for example, in: Watkins, “Handbook of Insecticide Dust Diluents and Carriers”, 2nd ed., Darland Books, Caldwell N.J., H. v. Olphen, “Introduction to Clay Colloid Chemistry”; 2nd ed., J. Wiley & Sons, N.Y.; C. Marsden, “Solvents Guide”; 2nd ed., Interscience, N.Y. 1963; McCutcheon's “Detergents and Emulsifiers Annual”, MC Publ. Corp., Ridgewood N.J., Sisley and Wood, “Encyclopedia of Surface Active Agents”, Chem. Publ. Co. Inc., N.Y. 1964; Schönfeldt, “Grenzflächenaktive Äthylenoxidaddukte” [Interface-active ethylene oxide adducts], Wiss. Verlagsgesell., Stuttgart 1976; Winnacker-Küchler, “Chemische Technologie”, Volume 7, C. Hanser Verlag Munich, 4th Ed. 1986.

On the basis of these formulations, it is also possible to produce combinations with other pesticidally active substances, for example insecticides, acaricides, herbicides, fungicides, and with safeners, fertilizers and/or growth regulators, for example in the form of a finished formulation or as a tankmix. Suitable safeners are, for example, mefenpyr-diethyl, cyprosulfamide, isoxadifen-ethyl, cloquintocet-mexyl and dichlormid.

Wettable powders are preparations which can be dispersed uniformly in water and, in addition to the active ingredient, apart from a diluent or inert substance, also comprise surfactants of the ionic and/or nonionic type (wetting agents, dispersants), for example polyoxyethylated alkylphenols, polyoxyethylated fatty alcohols, polyoxyethylated fatty amines, fatty alcohol polyglycol ether sulfates, alkanesulfonates, alkylbenzenesulfonates, sodium lignosulfonate, sodium 2,2′-dinaphthylmethane-6,6′-disulfonate, sodium dibutylnaphthalenesulfonate or else sodium oleoylmethyltaurate. To produce the wettable powders, the herbicidal active ingredients are ground finely, for example in customary apparatus such as hammer mills, blower mills and air-jet mills, and simultaneously or subsequently mixed with the formulation auxiliaries.

Emulsifiable concentrates are produced by dissolving the active ingredient in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene, or else relatively high-boiling aromatics or hydrocarbons or mixtures of the organic solvents, with addition of one or more ionic and/or nonionic surfactants (emulsifiers). The emulsifiers used may, for example, be: calcium alkylarylsulfonates such as calcium dodecylbenzenesulfonate, or nonionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide-ethylene oxide condensation products, alkyl polyethers, sorbitan esters, for example sorbitan fatty acid esters, or polyoxyethylene sorbitan esters, for example polyoxyethylene sorbitan fatty acid esters.

Dusting products are obtained by grinding the active ingredient with finely distributed solid substances, for example talc, natural clays, such as kaolin, bentonite and pyrophyllite, or diatomaceous earth.

Suspension concentrates may be water- or oil-based. They can be produced, for example, by wet grinding by means of commercial bead mills with optional addition of surfactants as already listed above, for example, for the other formulation types.

Emulsions, for example oil-in-water emulsions (EW), can be produced, for example, by means of stirrers, colloid mills and/or static mixers using aqueous organic solvents and optionally surfactants as already listed above, for example, for the other formulation types.

Granules can be produced either by spraying the active ingredient onto adsorptive granulated inert material or by applying active ingredient concentrates by means of adhesives, for example polyvinyl alcohol, sodium polyacrylate or mineral oils, to the surface of carrier substances, such as sand, kaolinites or granulated inert material. Suitable active ingredients can also be granulated in the manner customary for the production of fertilizer granules—if desired as a mixture with fertilizers.

Water-dispersible granules are produced generally by the customary processes such as spray-drying, fluidized bed granulation, pan granulation, mixing with high-speed mixers and extrusion without solid inert material.

For the production of pan granules, fluidized bed granules, extruder granules and spray granules, see, for example, processes in “Spray-Drying Handbook” 3rd ed. 1979, G. Goodwin Ltd., London; J. E. Browning, “Agglomeration”, Chemical and Engineering 1967, pages 147 ff.; “Perry's Chemical Engineer's Handbook”, 5th ed., McGraw-Hill, New York 1973, p. 8-57.

For further details regarding the formulation of crop protection compositions, see, for example, G. C. Klingman, “Weed Control as a Science”, John Wiley and Sons, Inc., New York, 1961, pages 81-96 and J. D. Freyer, S. A. Evans, “Weed Control Handbook”, 5th Ed., Blackwell Scientific Publications, Oxford, 1968, pages 101-103.

The agrochemical formulations contain generally 0.1 to 99% by weight, especially 0.1 to 95% by weight, of compounds according to the invention.

In wettable powders, the active ingredient concentration is, for example, about 10 to 90% by weight; the remainder to 100% by weight consists of the customary formulation constituents. In the case of emulsifiable concentrates, the active ingredient concentration can be from about 1 to 90, preferably from 5 to 80, % by weight. Dust-type formulations contain 1 to 30% by weight of active ingredient, preferably usually 5 to 20% by weight of active ingredient; sprayable solutions contain about 0.05 to 80% and preferably 2 to 50% by weight of active ingredient. In the case of water-dispersible granules, the active ingredient content depends partly on whether the active compound is present in liquid or solid form and on which granulation assistants, fillers, etc., are used. In the water-dispersible granules, the content of active ingredient is, for example, between 1 and 95% by weight, preferably between 10 and 80% by weight.

In addition, the active ingredient formulations mentioned optionally comprise the respective customary tackifiers, wetting agents, dispersants, emulsifiers, penetrants, preservatives, antifreeze agents and solvents, fillers, carriers and dyes, defoamers, evaporation inhibitors and agents which influence the pH and the viscosity.

On the basis of these formulations, it is also possible to produce combinations with other pesticidally active substances, for example insecticides, acaricides, herbicides, fungicides, and with safeners, fertilizers and/or growth regulators, for example in the form of a finished formulation or as a tankmix.

Usable combination partners for the inventive compounds in mixture formulations or in a tankmix are, for example, known active ingredients based on inhibition of, for example, acetolactate synthase, acetyl-CoA carboxylase, cellulose synthase, enolpyruvylshikimate-3-phosphate synthase, glutamine synthetase, p-hydroxyphenylpyruvate dioxygenase, phytoendesaturase, photosystem I, photosystem II, protoporphyrinogen oxidase, as described, for example, in Weed Research 26 (1986) 441-445 or “The Pesticide Manual”, 15th edition, The British Crop Protection Council and the Royal Soc. of Chemistry, 2009 and literature cited therein. Examples of known herbicides or plant growth regulators which can be combined with the inventive compounds include the active ingredients which follow (the compounds are designated by the “common name” according to the International Organization for Standardization (ISO) or by the chemical name or by the code number) and always encompass all use forms, such as acids, salts, esters and isomers, such as stereoisomers and optical isomers.

For application, the formulations in commercial form are, if appropriate, diluted in a customary manner, for example in the case of wettable powders, emulsifiable concentrates, dispersions and water-dispersible granules with water. Dust-type formulations, granules for soil application or granules for broadcasting and sprayable solutions are not normally diluted further with other inert substances prior to application.

The required application rate of the compounds of the formula (I) varies with the external conditions, including temperature, humidity and the type of herbicide used. It can vary within wide limits, for example between 0.001 and 1.0 kg/ha or more active substance, but it is preferably between 0.005 and 750 g/ha.

The examples which follow illustrate the invention.

A. Chemical Examples Synthesis of 2-chloro-N-(1,2,5-oxadiazol-3-yl)-6-(trifluoromethyl)nicotinamide (Table example No. 1-3)

C. Biological Examples 1. Pre-Emergence Herbicidal Action Against Harmful Plants

Seeds of monocotyledonous and dicotyledonous weed plants and crop plants are placed in wood-fiber pots in sandy loam and covered with soil. The inventive compounds formulated in the form of wettable powders (WP) or as emulsion concentrates (EC) are then applied to the surface of the covering soil as an aqueous suspension or emulsion at a water application rate of 600 to 800 I/ha (converted) with addition of 0.2% wetting agent. After the treatment, the pots are placed in a greenhouse and kept under good growth conditions for the test plants. The damage to the test plants is assessed visually after a test period of 3 weeks by comparison with untreated controls (herbicidal activity in percent (%): 100% action=the plants have died, 0% action=like control plants). Compounds No. 1-22, 1-108, 1-109, 1-23, 1-93, 1-207 and 1-90 at an application rate of 320 g/ha each show at least 80% efficacy against Abutilon theophrasti, Amaranthus retroflexus and Echinochloa crus galli. Compounds No. 1-17, 1-109, 1-93, 1-101 and 1-90 at an application rate of 320 g/ha each show at least 80% efficacy against Veronica hederifolia and Viola tricolor.

2. Post-Emergence Herbicidal Action Against Harmful Plants

Seeds of monocotyledonous and dicotyledonous weed and crop plants are placed in sandy loam in wood-fiber pots, covered with soil and cultivated in a greenhouse under good growth conditions. 2 to 3 weeks after sowing, the test plants are treated at the one-leaf stage. The inventive compounds formulated in the form of wettable powders (WP) or as emulsion concentrates (EC) are then sprayed onto the green parts of the plants as an aqueous suspension or emulsion at a water application rate of 600 to 800 I/ha (converted) with addition of 0.2% wetting agent. After the test plants have been left to stand in the greenhouse under optimal growth conditions for about 3 weeks, the action of the formulations is scored visually in comparison to untreated controls (herbicidal action in percent (%): 100% action=the plants have died, 0% action=like control plants). For example, compounds No. 1-88, 1-93, 1-100, 1-171 and 1-208 at an application rate of 80 g/ha each show at least 80% efficacy against Amaranthus retroflexus and Veronica hederifolia. Compounds No. 1-88, 1-93, 1-100 and 1-171 at an application rate of 320 g/ha each show at least 80% efficacy against Abutilon theophrasti and Stellaria media.
